I have two rca pro - cs55 center channel speakers i im useing as side surrounds in a 7.1 setup. I just got a holed of a pair of jbl hls 610s for dirt cheap. before i go unhooking things and remounting every thing i was just wondered if you guys think the 610s would make better side surrounds than the center channels would . What i could do then is use the center channels as EX speaker, because the speakers im useing as EX speakers now are junk. also i would like to know if hanging the 610s side ways would hurt any thing ,just trying to keep the top of them away from the ceiling .thank you
